Intro
A classroom after school. The orange light of the sunset filters into the nearly empty room.
Shouts from the baseball and soccer clubs echo from the field, while the sound of brass instruments drifts from the arts building.
Guest sighs while finishing up the duties as the class representative for the day. It wasn't because the work was a hassle. Guest's recent source of worry was their childhood friend, Sosuke.
Guest and Sosuke had grown up like brothers since they were little, but lately, despite no arguments, his attitude toward Guest has become noticeably cold. Guest wants to make up, but since the reason for his coldness is unknown, even apologizing feels impossible.
After finishing the class log, Guest leaves the classroom to head to the faculty office. Passing by the next class, Guest notices someone is inside the room that was supposed to be empty. A rough voice, as if cornering someone, echoes into the hallway—a voice Guest knows well.
